Goodness-of-Fit Test · Exercise 18

For each problem, use a solution sheet to solve the hypothesis test problem. Go to for the chi-square solution sheet. Round expected frequency to two decimal places.

A six-sided die is rolled 120 times. Fill in the expected frequency column. Then, conduct a hypothesis test to determine if the die is fair. The data in are the result of the 120 rolls.

$$\begin{array}{ccc}\text{Face Value}& \text{Frequency}& \text{Expected Frequency}\\ \text{1}& \text{15}& \\ \text{2}& \text{29}& \\ \text{3}& \text{16}& \\ \text{4}& \text{15}& \\ \text{5}& \text{30}& \\ \text{6}& \text{15}& \end{array}$$

Its source prints no answer for this problem, so there's nothing to check against.
